BENJAMIN W. TUCKER, OF NEWARK, NEW JERSEY, ASSIGNOR TO CHARLES H. UNVERZAGT,

` OF NEW YORK, N. Y.

MALT-STIRRING APPARATUS.

To all whom it may concern: v

Be it known that I, BENJAMIN W. TUCKER, a citizen of the United States, of 7 S4 Highland avenue, Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Malt- Stirring Apparatus, fully described and represented in the iollowing specification and the accompanying drawings, forming a part of the saine. l

The object of the present invention is to furnish an automatic mechanism for turning the grain upon a malting floor and conveying it therefrom when malted, and the invention comprises a carriage with a reversible grain-turning cylinder thereon and reversible vanes and valve-plates pivoted upon the cylinder, with means for traversing the cylinder back and forth over the malting alley and reversing the motion of the cylinder and the position oi the vanes automatically at the opposite ends of the alley.

The invention includes the means when the stirring` of the grain is completed, for automatically discharging the grain through the agency of the cylinder and an interior conveyer to an adjacent alley or to a channel. from which the grain may be discharged to any desired point,

Where a plurality of malting alleys can be operated side by side, the invention furnishes a means, through a movable cradle mounted upon a transverse track at the ends of the alleys, for receiving the carriage from any of the alleys and transporting it to another alley, so that the grain-turning device may be kept constantly in use.

The invention will be understood by reference to the annexed drawing, in which Figure l is a plan ot' three malting alleys upon the saine Hoor with the carriage upon one of such alleys and a cradle at the end of the alley for transporting the carriage to one oi the other alleys; Fig. 2 is an end elevation of one of the alleys with the cylinder and its carriage in section at one side of the broken line x-af; Fig. 3 is an end view oi the carriage and turning-cylinder; Fig. 4 is a cross section ot' the turning-cylinder taken on line 4 4 in Fig. 2; Fig. 5 is an end View of the cylinderhead and supporting-disk; Fig. 6 is a section on line (56 in Fig. 5; Fig. 7 shows the lower end of one of the heads ol' the vane-shell; and Fig. S shows on a reduced scale one oi the carriage-frames. Fig. 9 is a plan of the valve-plate turning mechanism', and Fig. l0 is a section on line lOlO in Fig. 9. Fig. ll is a side view of the hub oi the segment p. Fig. l2 is a perspective View oi the transfer cradle.

In Fig. l, A, B, C, designate three malting alleys each having retaining walls a at its opposite sides to hold the grain therein. A channel a is shown between the adjacent alleys. The top of each wall is provided Specification of Letters Patent.

with rail b to receive the truck-Wheels c of the cylindercarriage, which is formed with frames d connected by tie-bars or beams e. The beams carry a trough f, the ends of which extend over the channels a and the beams also carry a series of disks (7, y, to which annular heads h upon the cylinder are fitted movably, such heads having wheels 2' litted to Contact with the edges oi the disks, and such edges being rabbeted, and anges h upon the heads Iitted movably to such rabbets to prevent longitudinal movement. Vane-shats j are extended through and between the heads near their periphery, and vanes formed with ends c and quadrantal shell c/ are attached to such shafts. A slotted rocker-arm l is attached to the end of each vane-shaft, and a ring-gear m is fitted to the head h adjacent to such arms and provided with a series of studs n to engage the slots in the arms. The turning of such ring upon the head as hereinafter described, operates to turn the shells of the vanes from their left hand position, shown in full lines in Fig. 3, to the right hand position indicated by the dotted line k2 in Fig. 3, the arms Z then assuming a reverse position to that shown in Fig. 3, as indicated in the dotted lines l for one of the arms, adjacent to the dotted vane k1.

The forward edge of each vane, when in operation, lies directly outside of the vane-shaft, as shown in Fig. 4, the opposite edge of its quadrantal shell touching the periphery of the head h, and a valve-plate o is shown joiunaled upon each vane-shaft by hub o and is adapted to close the space o2' between the vaneshaft and the inner edge o the vane, when it is desired to retain the grain within the vane. Such position of the valve-plates 0 is shown upon all of .the vanes in Fig, 4, excepting the upper one, in which the plate is turned to open the inner end of the vanespace 02, which then stands directly over the trough f; so that the contents oi the vane is discharged by gravity into the trough. Such turning of the valve-plate is effected, when the vane reaches its uppermost position, by toothed segments p mounted to turn upon shafts 1' which serve as tie-bars between the heads h, such segments engaging pinions p upon the hubs 0/, and tail-pieces p2 projected from the `toothed segments to engage a cam q which is movable into the path of the cranks by a hand-lever g.l The tie-bars 1 are immovable in the heads h and the segments turn thereon and are held normally in a central position thereon by springs r strained in opposite directions and each attached at one end by a collar r3 to the tie-bar, and having at its other end a collar T5 provided with a lug r4 to engage a tooth 1'2 upon the hub of the segment p as shown in Figs. 9 to ll. Each collar T5 has a slot s3 tted to a pin s4 upon the shaft r the pins holding the collars 15 with the lugs r4 in contact with opposite sides of the tooth r2 so as to hold the segment normally in a central position, which is indicated for all of the segments and the valve-plates, except the upper one in Fig. 4. The slot s in either collar 15 permits the segment tooth to rotate the collar when the segment is moved. Pressure upon the cranks p2 in either direction turns the segment in opposition to one of the springs r, such spring restoring the segment to its central position as soon as the crank has passed off of the cam q, and carrying the segment to the centralposition, by the contact of the stop-pin s4 with the end of the slot s3. When the crank q2 is in the position shown in Fig. 4, it'holds the cam q in the path of the tail-pieces p2, and the cam-face is of just sufficient length to shift each of the vane-plates and open the vane-space while the vane is moving over the trough f. When the handlever 2/ is turned to the left from the position shown in Fig. 3, it lowers the cam q from the path of the cranks ,fo2 and permits the cylinder to revolve continuously with all the valve-plates closed, so as to pick up the grain and spill it upon the opposite side of the cylinder.

In Fig. 2, bearings r4 are shown upon the tie-bars r adjacent to the collars r3, and such bearings are in practice mounted by means of two legs upon the beams e at the opposite sides of the trough f; but the legs which supportthese bearings upon the beams e are not shown in the drawings, as they would confuse other parts. The relation of the bearings to the beams is, however, apparent by inspection of Fig. 4, where the tie-bar r appears above the middle of the trough, as the legs of the bearings would straddle over the top of the conveyer s in a manner similar to that in which the cam q is arched over the top of the trough, while its connections extend to both of the beams e.

In the design of turning-cylinder shown, one of the disks g is required at each end of the cylinder and a disk g/ at the middle thereof, and Fig. 2 shows the cylinder shortened by breaking out a portion adjacent to the middle disk, it being understood that the length of the cylinder, which is not shown in section at the right hand side of such center disk, would be the same as the length which is shown in section at the left hand side of the center disk. The rotary motion of the turning-cylinder is reversed at each end of the malting alley and the cranks p2 thus engage the cam q from the opposite ends of the cam, when lthe cylinder rotates in opposite directions; but the vanesare also reversed at each end of the malting alley, and the reverse operation of the segments thus opens the bottom of the vanespace equally when the cylinder turns in either direction.

The means for turning and propelling the turningcylinder is so constructed that it may automatically reverse the rotations of the cylinder at the ends of the malting alley, and simultaneously reverse the position of the vanes, the ordinary operation of turning the grain requiring the bottoms of the vanes to be held closed continuously so that the grain may be lifted over the cylinder and deposited upon the other side.

When the grain has been fully malted, the handlever q is moved as shown in Fig. 4, to lift the cam q, and all of the grain lifted by the cylinder is thereafter deposited in the trough f and delivered to the channels a. These channels are provided with conveyers a2 for moving the grain longitudinally therein, and openings a3 are shown in the bottoms of the channels in Fig. l, through which the malted grain may be delivered to any apartment or bin, as may be desired.

The spiral blades of the conveyer s are shown inclined in opposite directions from the middle line of the trough, as in Fig. 2, so that the grain as it falls into the trough is discharged equally toward both ends of the trough and delivered into the channels a.

The cylinder is shown operated by a motor E, mounted on one of the carriage-frames d, and connected by worm and worm-wheel E/ with the conveyer-shaft s in the trough f,and the farther end of such conveyer shaft is connected by suitable gearing with a crossshaft D mounted in bearings D/ upon the other frame d to rotate the turning cylinder and propel the carriage.

The shaft D is connected by worm u and worm-wheel u with a shaft t carrying pinions t which mesh with rack-teeth t2 upon the tops of the Walls, the shaft t being journaled in the frames d and extending between the same through the disks g, g/. The cylinder is rotated by a ring-gear m having internal teeth, which is driven by a cog-wheel m upon a gear-shaft I. This shaft carriesa worm-wheel o driven by a worm o" upon the cross-shaft D.

The ring-gear '1n is mounted upon the end head h of the cylinder, so as to slide thereon through an arc of about twenty degrees, which movement occurs when the rotation of the ring-gear m is reversed, as hereinafter described, to reverse the rotations of the cylinder. This motion of the ring-gear is utilized to automatically reverse the position of the vanes, by the engagement of the studs n with the rocker-arms Z, causing the shifting of the rocker-arms and the vanes, as already described in reference to Fig. 3. The margin of the ring-gear m is guided as indicated in Fig. 2, by rabbeted gibs m2, and the movement of the ringgear is limited by the movement of the studs n in the slotted arms Z, and by the contact of the shells of the vanes with the peripheries of the heads h, as shown in Fig. 4. The reversal of the movement of the ringgear m thus operates first to turn the ring-gear upon the head and reverse the vanes and thereafter to propel the ring-gear and cylinder as a unit.

The rotation of the shaft s/ requires to be continuous in one direction, so that the conveyer s may always deliver the grain toward the ends of the trough, but to reverse the rotations of the cylinder and its movement between the walls a, the conveyer-shaft s is provided with a bevel-gear s2 upon'its end which meshes with bevel-gears F and F upon the cross-shaft D, turning such gears in opposite directions. The gears F and F are fitted with sleeves to turn loosely upon the crossshaft D, each sleeve having a clutch-plate bi Clutchhubs b2 are splined to the cross-shaft and may be thrown alternately into engagement with the bevel-gears F and FQ by lever-arms w and a handle wf. The shifting of this handle serves to reverse the rotations of the crossshaft D and consequently the rotary movement of the cylinder and the motion of the carriage upon the walls, and such shifting may be effected automatically near the ends of the malting alley, by a suitable dog indicated one at each side of the cylinder at w2 in Fig. 3. The left hand dog, by contact with the handle, shifts it sufciently to retract the clutch from the clutchplate of the bevel-gear F and engage the opposite clutch with the clutch-plate of the gear F. One of the dogs would, in practice, be xed upon the wall or ceiling adjacent to each end of the alley which the carriage is designed to traverse, and the car'riage would thus be driven back and forth upon such alley so long as the power was applied. The handle W, as shown in Fig. 2, projects farther from the end of the cylinder than any of the other parts, and the dog designated w2 in Fig. 2 could thus operate such lever without interfering with the handle q or any other part upon the carriage.

When the grain is sufficiently rnalted, the carriage and turning-cylinder may be run from the track b to rails b upon the transverse cradle shown in Figs. l and l2, which is formed with side-beams G and end-beams Gf. The beams G carry track-wheels H journaled thereon to fit transverse track-rails I/ upon the floor across the ends of adjacent alleys. The beams G have rails b thereon which, when the cradle is set at the end of an alley, form extensions of the rails b upon the Walls a of the alley, so that the car'riage with the turning cylinder may be wheeled on to the cradle and moved to the end of another alley. When thus moved, it may be shifted upon the track-rails b of such alley and operated thereon in the manner already described.

In Fig. 2, the walls a are shown` hollow with apertures y next the alley for discharging a heating or cooling fluid into the grain while the turning cylinder is agitating the grain. Airor water, either hot or cold, or steam, may thus be supplied to the grain. Pipes y are shown extended into the chambers within the walls a, and suitable connections may be made to such pipes for supplying the fluid as required.

It will be noticed by reference to the left hand end of the cylinder, which is shown in section in Fig. 2,

that the openings o2 to which the grain is discharged from the vanes to the trough f cannot extend to the ends of the cylinder', and in order that the grain lifted by the vanes may be fully discharged into such openings, the heads k of the vanes are formed as with a double inclined surface with the apex at the inner side of the head, as shown in Fig. 7, the ends of such inclined surfaces forming scrapers k3 which move close to the walls a of the malting-floor and thus clean the grain effectively therefrom. Tapering blocks ct shown in Figs. 2, 3, and 5, are formed upon the heads h at the opposite ends of the openings o2, against which blocks the sloping edges of the heads k rest, as shown in Fig. 3, when the vanes are in their operative position; thus holding the grain away from the rear edge of the vane and throwing toward the openings o2 the grain which is lifted by the forward edge of the head.

A trolley or flexible conductor may be used to convey the current to the electric motor, but any other power beside an electric motor may be used to actuate the turning cylinder.
